Был crash-restore режим. OpenWRT шьется именно в таком режиме.
Вот (
отсюда):
First you've got to wire the router from the build machine to LAN port 1, and
bring the router up in diagnostic mode. The latter is accomplished by:
* make sure the router is powered off
* hold down the reset button on the back
* plug in the power
* don't release the reset button until the power light flashes on and off at 1Hz
Then! Execute the above commands (
здесь идет речь о tftp), and you should see a lot of block transfers scrolling by. When those complete wait a while; wiki knowledge suggests 6 minutes, but my WL500GP-V2 completes the flash inside of 30 seconds. Mostly you should have a console connection so you can get positive feedback for all this.
Вот, кстати, цитата из web-морды (не Ваш ли случай?):
In case the upgrade process fails, WL500g.PremiumV2 will enter an emergent mode automatically. The LED signals at the front of WL500g.PremiumV2 will indicate such situation. Use the Firmware Restoration utility on the CD to do system recovery.
